UNITED STATES PATENT oFFlcE WINDING REEL Application January 16,'1933,Serial-No. 652,089 Renewed June 15, 1939 30 Claims.

, This invention relates to a winding reel for the manufacture of threador the like, as, for example, artificial silk thread. The invention hasto do with a reel of this type by and upon which the thread or the likeis Wound in a manner permitting it to he subject-ed in a relatively longlength to any processing operations to which it may be desired to exposeit. The Winding reel of the present invention may be regarded as animprovement upon the type of reel shown and described in a priorapplication for Continuous spinning machine, Serial No. 651,404, ledJanuary 12. 1933, to which reference may be had if desired. It may alsobe treated as an improvement upon the severa-l types of reelsrespectively shown and described in United States Patents Nos. 34,494,1,052,125, and 1,983,221.

An object of the present invention is to provide a simple, improved reelof the character described consisting of two like members, both of rigidform, closely associated in the sense that they are more or lesssuperimposed upon each other or occupy substantially the same space, buthaving their axes displaced with relation to each other.

for the purpose of advancing, turn by turn, thread or the like led toit, all with dependable uniformity and regularity of action, Withoutharmful effect upon the thread or the like, and in a manner to avoiderrors in operation as the result of wear and tear in the apparatusf Afurther object of the invention is to provide a reel of this kindgwhichcan be made in any desired length within reasonable limits; which canadvance one thread or thread-like article or. if desired, a plurality ofthreads or thread-like articles, the several threads or thread-likearticles being kept separate from each other; and in which the mechanismneed embody only .relatively simple bearings. and driving means, andother parts.

o Further objects of the invention are in part obvious and will in partappear more in detail hereinafter.

In the drawings, Fig. 1 represents a plan of one form of reel embodyingthe invention; Fig. 2

is a corresponding explanatory diagram; Fig. 3

is a sectional elevation, more or less diagrammatic. illustrating threereels coordinated into a machine and cooperatively rela-ted to aspinning device: Fig. 4 is an elevation of the reels, as seen from theleft in Fig. 3; Fig. 5 is an end elevation of the reel from the right inFig. l; Fig. 6 is a corresponding explanatory diagram; and Fig. '7 is asectional elevation of the reel on substantially the line 1 -'1, Fig. 5.While the invention may be employed under any conditions making itdesirable to provide a reel capable of advancing thread or the like orof storing a considerable length of thread or the like, so as to serveas a store device therefor, the invention is illustrated in the drawingsand will 5 be described hereinafter as employed as an element of acontinuous spinning machine for the production of artificial silkthread, particularly a machine .of the kind in which a separate step ofthe process is yperformed upon the thread on each 10 of `a plurality ofreels to which the thread is led in succession, all as generallydescribed in the prior application above referred to. It is obvious,

however, that the reel is not limited in its usefulness to continuousspinning machines for the 15 manufacture of artificial silk thread, butmay to advantage be employed, -either alone or in association withotherreels, in a-wide variety of machines of Wholly different types.

While the invention may be usedwith any of 20 the Well known processesfor producing articial silk thread, such as the cuprammonium, cellulosea-cetate, cellulose nitrate and the viscose processes, it will forconvenience Ibe described only in connection with the practice of theviscose 25 process. Referring first to Figs. 3 and 4, trough I isillustrated as containing a coagulating bath 2 intovwhich the viscose isextruded through the usual spinneret 3, the multiple filament thread 4being led through suitable guides 5 to the rst of a series of rotatingreels 6, 6a, 6b, each of which is designed to receive the thread, formit into a series of helical turns spaced at relatively short intervals,and advance it bodily along the reel toward its opposite end'to atake-off point from 35 which the thread is led to the next reel. It isof course understood that on each of said reels a different step of theprocess of manufacture is performed upon the thread until the latteriinally emerges in completed or partially completed form ready to begathered upon a collecting device. The present invention has to do withthe specic form of the reels employed'.

In the arrangement shown in Figs. l, 5 and '7, the reel comprises tworeel members 1, 8, each of 45 which constitutes a self-contained rigidstructure having its periphery, which v is of substantially circularcross section, defined Iby a series of longitudinally extending parallelbars or bar-like members.

the same space. Each reel member comprises not only the longitudinalbars aforesaid, but a supporting structure which may be of spider, wheelor disc form with a'central hub. The supporting structures of the tworeel members are sufficiently spaced longitudinally from each other sothat said members can occupy substantially the sa-me space, as stated.

In the arrangement shown, the reel member 1 is provided with asupporting structure consisting of a spider or disc 9 secured to a shaftI0, as by the set screw II, said spider or disc 9 carrying at itsperiphery a series of longitudinally extending bars I2 which extendlongitudinally in both directions from the spider or disc 9, the latterbeing a spider or disc I3 carrying a series of like longitudinallydisposed bars I4 on its periphery, but in this case the spider or discis shown as disposed at one end of the reel member andthe bars projectlongitudinally in one direction only from the spider or disc, thearrangement being such that the bars of the two reels lie side by sideand are coextensive longitudinally. Reel member 8 is also shown as atrue cylinder in. the sensel that the outer vedges or surfaces of itsbars form elements of a cylindrical surface, but it is not coaxial withthe shaft I0. The bearings for its spider or disc I3 are carried by aportion of the machine frame I5 and are so arranged that the axes of thetwo reel members are displaced from each other in two respects, as willhereinafter appear.

First, the axes of the two reel members are displaced laterally fromeach other by a uniform amount along the full length of the reel and,second, the axis of one reel member is canted to a-n inclined positionwith reference to the axis of the other reel member. The axes of thereel members are thus in skew relation to each other. In other words,looking at the diagrams, Figs. 6 and 2, which greatly exaggerateconditions, reel member 'l is assumed to be coaxial with the shaft I0and the reel member 8 has been displaced laterally with relation tomember 'I until the reel members are entirely separated from each other,as shown in Fig. 6, and reel memlber 8 has been canted to an inclinedposition with relation to member 1, as shown in Fig. 2. As amatter offact, in a reel of say ten inches in diameter, the parallel displacementmay amount to say oneeighth of an inch and the cant shown in Fig. 2 mayamount to a matter of only a very degrees, say seven-sixteenths of aninch in a total reel length of forty-eight inches.

Thus in the preferred embodiment of the invention the axes of the reelmembers may be dened in geometrical terms as represented by skew lines.

The number of bars in the two reel members may vary, but, other thingsbeing equal, the total number of bars should be as large as possibleconsistent with proper construction, operation, etc. As shown in Fig. 5,the bars of the two reel members preferably alternate with each other.Also, one of the reel members; to wit, reel member I in the form shown,serves as a driving member and the other, reel member 8 in the formshown,

serves as a driven member. Member 8, as shown in Fig. 7, is journalledupon a bearing of tubular form carried by the fixed frame I5, whichbearing is so disposed as to be displaced from the axis of shaft I0 inthe two particulars above mentioned.

With this arrangement, when shaft IIJ is driven, the two reel membersrotate together or as a unit, one driving the other by bar to barengagement. The lateral displacement of the axes of the two reel memberscauses the bars of the driving reel member 1 to project outward beyondthose of the other member 8 during a part of a complete rotation, saythrough the lower 180 in Fig. 5, and the bars of the driven member toproject outward beyond those of the driving member through the otherhalf of the complete rotation, the upper 180 in Fig. 5. This back andforth relative radial motion of the two sets of bars makes possible atransfer of the turns of.thread from one reel member to the other.Furthermore, the canted disposition of the driven reel member 8 producesbodily advance of portions of the thread which are carried by it duringthat portion of the complete rotation when its bars are supporting thethread, to wit, during the upper half of the complete rotation, as shownin Fig. 5.

The total effect is to cause a thread led to one end of the reel to bewound upon the reel in substantially helical form, turn after turn, withthe succession of turns bodily advanced toward the far end of the reel.In this manner a thread led to the reel can be stored upon it in theform of a large number of very closely spaced turns, even as many asfifty to two hundred turns, and if the reel is of relatively largediameter, say ten inches, it is possible to store upon it a very longlength of thread, even as much as five hundred feet. 'I'hus if a bath oftreating liquid is showered upon or otherwise applied to the reel, agiven portion of the thread will be subjected to said bath for amaterial length of time, depending upon speed of rotation, number ofturns and lead of the thread helices, etc.

Obviously, the amount of lead or the spacing of turns of thread fromeach other depends upon the amount of cant, in other words, the secondfactor in the displaced relation between the two reel members beforereferred to and by varying the amount of such cant any desired lead maybe obtainedwithin limits.

The skew relationship of the axes of the reel members characterizing thepreferred ambodiment of the invention may be arrived at in various ways.If it is assumed that the final relative positions of the reel membersare reached by lrst laterally displacing them and then turning themabout an imaginary axis radial to the shaft I0, it will readily beperceived that such axis may be located at any point along the length ofthe reel as a whole, or, in other words, at any one of a number ofpoints, three of which have been marked X, Y and Z in Fig. 1. In thereel shown, the cant has been accomplished by twisting reel member 8about an imaginary radial axis at the point Y and the cant is thereforebalanced or equal but in opposite directions on opposite sides of theaxis Y longitudinally of the shaft. If, however, the inclination isaccomplished by canting reel member 8 around axis X or axis Z, all ofthe angular relationship will be on the same side of such axis. Twistingabout axis Y produces a reel which is more or less hour-glass in shape,while twisting about axis X or axis Z produces a reel which is more orless conical in shape.

ber. In other words, referring to Fig. 2, when the canted reel member istwisted or turned clockwise in Fig. 2, as shown in full lines, theyturns of thread will be bodily advanced toward the right, but if thecanted reel member is turned counterclockwise to the position indicatedin dotted lines, Fig. `2, the thread turns will move to the left. Byproper organization of the reel members on successive reel units thethread may be led back and forth in the manner shown in Fig.,4,travelling to the right on reel 6, to the left on reel 6a, to the righton reel 6b, etc.

In the arrangement shown in Figs. 1 to 7 inclusive, each reel isdesigned to support a single thread in the proper number of turnsthereof but if desired the reel may be made long enough to support aplurality of threads simultaneously led to it.

Of course, since the reel is drenched by the bath `of liquor showeredupon or otherwise applied to it for treatment of the thread, it isobvious that the reel and all of its parts, including supports, etc.,should be made of materials Which are not laffected by and do not aifectthe bath liquors, as will be readily understood. In general,chemical-resistant materials will be employed throughout with thepossible exception of reels used only for washing, drying or likeoperations not involving the use of corrosive reagents. Obviously, acidresistant materials, Whether metallic or non-metallic, willl be used inreels coming into contact with acids, as, for example, in reels used inconjunction with the coagulating bath in the viscose process ofmanufactur'ing artiiicial silk thread.

While in the foregoing description frequent reference has been made, forpurposes of i1- lustration, to the produ-ction of artificial silkthread, it is to be understood that the winding reel of the presentinvention has many and varied uses not in any Way connected withartificial silk thread or, for that matter, with the various stepsinvolved in the actual manufacture of thread of any particular kind. Itis obviously vcapable of use in the manipulation and/or processing ofthread quite apart from the method of its manufacture, regardless ofwhether .the

thread so manipulated or processed is of natural or synthetic origin. Asa matter of fact, the,

winding reel of the present invention is suitable for use not only inconjunction with the manufacture, manipulation and processing of thread,but also in conjunction with the manufacture, manipulation andprocessing of other articles that, speaking in the broadest sense, areof generally thread-like character. I'hese articles it is intended toinclude, together with thread, Within the scope of such genericexpressions as thread or the like and thread-like article as used in thespecification and claims hereof.
